I
might have to order more soon. im running outa the 3mm. im using them in my speedometer gauge cluster, i replaced all the 5 bulbs that were in the cluster w/ clusters of 4 - 3mm leds w/ no resistors. they light up good, but not enough, its brighter in some places more then others, so i guess im gonna have to drill holes and glue some more led's in like citation did to get it more even.. crap
